Heat exchanger with fluid control means for controlling a flow of a heat exchange medium and method of manufacturing the same

摘要

At least one flow control member (127a) is fitted in a fitting groove (133) formed in a tank (121). An insertion hole (204) is formed in at least a part of the fitting groove (133). The flow control member (127a) has a projection (205) to be inserted into the insertion hole (204). The projection (205) is smaller in size than the insertion hole (204). The flow control member (127a) is arranged at a predetermined position within the tank (121). The fitting groove (133) is defined by a pair of side wall portions (203b) formed by internally cutting a tank wall of the tank (121) in a thickness direction along a pair of parallel cutting lines, and a guide portion (203a) formed by extruding a portion of the tank wall between the side wall portions (203b). The insertion hole (204) penetrates the guide portion (203a). The projection (205) has first and second tapered portions (351, 352, 354, 355) so that the thickness and the width are reduced towards the top end.
